Hi,

Seems dust is not working well with null safety and the newest dart.

dart run bin/dust.dart example/crash_on_bad.dart 
Unhandled exception:
Observatory did not start on 7575
output:

Was this ever resolved? I am having the same issue running on M1 Mac.

The issue is caused by an outdated path in lib/src/vm_controller.dart to '.pub-cache/global_packages/dust/bin/controller.dart.snapshot.dart2'.

The current controller snapshot in pub_cache is called controller.dart-2.16.2.snapshot therefore to resolve this run

cp ~/.pub-cache/global_packages/dust/bin/controller.dart-2.16.2.snapshot ~/.pub-cache/global_packages/dust/bin/controller.dart.snapshot.dart2

to make the hardcoded path point to a valid controller snapshot.

Awesome, Thank you for the hint. It works!
